Detailed Description

A deliberately badly-configured job to demonstrate a crash in
sub-event scheduling.

The ViewTester is an algorithm specifically designed to create sub-event
contexts, pass them to the scheduler, and report on the current context.

The re-use of filter_alg causes the CF to "skip over" filter_alg2
This would then cause sub-events to be scheduled, but with the
"ShortCircuit" property of the hltStep node set True, the event can
be deleted before the sub-events have completed, causing the crash.

There is now protection in AvalancheScheduler against this crash,
but note that re-using algs in this way is still expected to cause
surprising CF behaviour.
